Abstract
An AWD drivetrain is configured to primarily direct drive torque from a transversely-aligned powertrain assembly through an auxiliary power transfer unit to a rear driveline and selectively transmit drive torque to a front driveline via actuation of at least one power-operated clutch. The auxiliary power transfer unit includes an input component drivingly connected to the powertrain assembly, and an output component connected to the input component by a hypoid gearset The output component is operatively connected to the rear driveline and is configured to normally transfer the drive torque to the rear driveline.
Claims20
A drivetrain for a motor vehicle, comprising:
- a powertrain assembly configured to transmit drive torque to a front driveline and a rear driveline;
- an auxiliary power transfer unit including, an input component drivingly connected to said powertrain assembly and an output component operatively connected to said rear driveline, said auxiliary power transfer unit configured to deliver at least a portion of the drive torque to said rear driveline;
- and
- a power-operated clutch configured to transmit a portion of said drive torque from said auxiliary power transfer unit to said front driveline when said power-operated clutch is in an engaged state.
A drivetrain for a motor vehicle, comprising:
- a powertrain assembly configured to transmit drive torque to a front driveline and a rear driveline;
- a final drive gearset and a front differential assembly driven by said powertrain assembly;
- an auxiliary power transfer unit including an input component driven by at least one of said final drive gearset and said front differential assembly and an output component operatively connected to said rear driveline;
- a power-operated mode clutch movable between a front-wheel drive position wherein said power-operated mode clutch disengages said input component of said auxiliary power transfer unit and a rear-wheel drive position wherein said power-operated mode clutch engages said input component of said auxiliary power transfer system.
An all-wheel drivetrain for a motor vehicle, comprising:
- a powertrain assembly configured to transmit drive torque to a front driveline and a rear driveline;
- an auxiliary power transfer unit including an input component drivingly connected to said powertrain assembly, an output component connected to said input component by a hypoid gearset and operatively connected to said rear driveline and configured to normally transfer at least a portion of the drive torque to said rear driveline;
- and
- said auxiliary power transfer unit including a power-operate clutch configured to selectively transfer at least a portion of the drive torque from said input component to said front driveline.
